CX-LFA600 SECTION 1 SERVICING NOTES
Notes on chip component replacement · Never reuse a disconnected chip component. · Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing · Keep the temperature of the soldering iron around 270 °C during repairing. · Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). · Be careful not to apply force on the conductor when soldering or unsoldering. Unleaded solder Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.) : LEAD FREE MARK Unleaded solder has the following characteristics. · Unleaded solder melts at a temperature about 40°C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! · Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. · Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the "S curve check" in "CD section adjustment" and check that the S curve waveforms is output three times. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the exterior.
SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

Check the level B of the oscilliscope's waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than ± 10%

TP2 (TE) TP6 (RFDC) TP4 (FE)
Center of the waveform B
0V
A (DC voltage) level: 1.0 ± 0.5 Vp-p
Press the CD u button. (The tracking servo and sledding servo are turned ON) Rotate RV101 on BD board and adjust the C (DC voltage) is almost equal to the A (DC voltage) in step 4. 7. To exit from this mode, turn the power off.
Notes: · Always move the optical pick-up to most inside track when exiting from this mode. Otherwise, a disc will not be unloaded. · Do not run the sled motor excessively, otherwise the gear can be chipped.

NOTE: · Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. · -XX, -X mean standardized parts, so they may have some difference from the original one. · Items marked "*" are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items.
SECTION 9 ELECTRICAL PARTS LIST
· · CAPACITORS: uF: µF RESISTORS All resistors are in ohms. METAL: metal-film resistor METAL OXIDE: Metal Oxide-film resistor F: nonflammable COILS uH: µH · SEMICONDUCTORS In each case, u: µ, for example: uA...: µA... , uPA... , µPA... , uPB... , µPB... , uPC... , µPC... , uPD..., µPD...
When indicating parts by reference number, please include the board name. The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.
